    DEVICE FOR ROTATING ANIMAL DEJECTIONS IN A RIGOLE
    The present application relates to a device for scraping animal dung in a channel.
    For some husbandry techniques, animal dung and wastewater are collected in ground-level ditches.
    According to one embodiment, the floor and the channel are made of concrete and each channel has an approximately square or rectangular section.
    A scraping device is generally associated with each channel to scrape and convey the droppings to one end of the channel.
    According to one embodiment, a scraper device comprises a frame equipped with two pads that slide on the bottom of the channel, one at each angle, and a scraper secured to the frame whose width is approximately equal to that of the channel. This scraper is connected to the frame by a pivoting connection to enable it to pivot between an active position in which its lower edge is positioned near the bottom of the channel and a raised position in which its lower edge is spaced from the ground.
    To move the scraping device from one end to the other of the channel, the scraper device comprises a traction cable to which the frame is connected and which extends from one end to the other of the channel and a cable drive mechanism positioned at at least one end of the channel and configured to move the frame in a first direction of movement called scraping direction and in a second direction of displacement opposite the first called return direction.
    According to one configuration, the scraper is pivotally mounted relative to the frame along a substantially horizontal pivot axis and perpendicular to the length of the channel. The traction cable is secured to a rod movable in translation relative to the frame between a first position which corresponds to the active position of the scraper and a second position which corresponds to the raised position of the scraper. This rod comprises a fork which cooperates with the upper edge of the scraper. Thus, when the pulling cable is pulled in the scraping direction, the rod moves to the first position and the fork rotates and holds the scraper in the active position. When the pull cable is pulled in the return direction, the rod moves to the second position and the fork rotates and holds the pig in the raised position.
    To reduce the stroke of the rod, the pivot axis is disposed near the upper edge of the wiper.
    This scraping device is not fully satisfactory for the following reasons:
    According to a first drawback, the friction of the chassis pads on the bottom of the channel causes premature wear of the concrete channels which must therefore be restored after a certain number of cycles.
    According to a second disadvantage, because of the presence of the pads, the lower edge of the scraper is spaced from the bottom of the channel even in the active position so that there always remains a film of waste or wastewater on the bottom of the channel that is a source of bad smells.
    According to another drawback, the traction cable being maintained only at each of its ends, it tends to hang and touch the bottom of the channel. The repeated friction of the steel cable on the bottom of the channel tends to generate a bleeding in the concrete which accentuates the second disadvantage. In the case of an installation as described in document FR-2.971.671, the friction of the cable tends to shear the coating provided in the channel.
    Finally, given the pivoting mechanism of the scraper, the lower edge of the scraper may not be sufficiently spaced from the bottom of the channel in the raised position.
    FR-2.134.281 discloses a scraper device which comprises a wiper movable between a vertical position and an inclined position. According to a variant that can be seen in FIG. 2, the movement of the scraper in one or other of the positions is controlled. For this purpose, the scraper device comprises a frame in two parts, a first part connected to an operating cable and a second part supporting the scraper. The latter is connected by a rod to the first part of the chassis. When the operating cable is pulled in a first direction, the first part of the chassis approaches the second part of the frame and pushes the scraper vertically. When the operating cable is pulled in a second direction, the first part of the frame deviates from the second part of the frame and pulls on the rod which causes pivoting and holding the scraper in an inclined position.
    The device described in document FR-2.134.281 is not fully satisfactory for the following reasons:
    The operating cable is positioned in a groove made at the bottom of the channel. This bleeding can not be cleaned so that animal droppings accumulate there which makes it difficult to move the operating cable and the first part of the frame.
    According to another problem, the two parts of the frame rub against the walls of the channel which causes premature wear of the channel. One could consider mounting the two parts of the chassis on wheels. However, the fact that the frame is made in two parts movable relative to each other, mounted on wheels makes the complex complex and difficult to guide.
    Finally, the tilting of the wiper from one position to the other is caused by the approximation and spacing of the two parts of the frame. However, waste can accumulate between the two parts of the frame and make it impossible to bring them together and tilting the scraper in the vertical position.
    The present invention aims to overcome the disadvantages of the prior art. For this purpose, the subject of the invention is a scraper device which comprises: a frame configured to move in a longitudinal direction in a channel, a scraper connected to the frame by a pivoting connection with a substantially horizontal pivot axis and perpendicular to the longitudinal direction, said scraper being configured to occupy in operation an active position in which the scraper is positioned in a substantially vertical plane and a raised position in which the scraper is inclined and spaced from the bottom of the channel, a control which comprises a rod connected to the frame by a slide connection, said rod being movable in the longitudinal direction relative to the frame between a first position in which the rod is in contact with a first stop and which corresponds to the active position and a second position in which the rod is in contact with a second stop corresponding to the has raised position. According to the invention, the control comprises a connecting rod which connects the rod and the scraper.
    This configuration makes it possible to convert a very short translation movement of the rod into a wide pivoting movement of the scraper which passes from a vertical position to a horizontal position. Thus, the scraper is substantially horizontal in the raised position.
    According to other characteristics taken separately or in combination: the pivot axis of the pivoting connection connecting the scraper to the frame is positioned so that the mass of the scraper is distributed in a balanced manner on either side of said pivot axis; the scraper comprises: O a rigid plate with a lower edge and two lateral edges respectively oriented towards the bottom and the side walls of the channel, the rigid plate being dimensioned so that at least the lower edge of the rigid plate is removed from the bottom when the wiper is in the active position, O at least one flexible strip attached at least at the lower edge which projects from the rigid plate and which is dimensioned so as to come into contact with the bottom of the channel when the scraper is in the active position; the scraper comprises flexible strips at the lateral edges of the rigid plate; each flexible band is connected to the rigid plate by a removable connection; the chassis comprises at least three wheels configured to roll on the bottom of the channel; the chassis comprises a self-centering system which comprises at least three wheels configured to bear against the two side walls of the channel.
    According to another characteristic, the scraper device comprises a cable connected to the rod which extends along the length of the channel and at least one holding system for holding the cable away from the bottom of the channel. Other features and advantages will become apparent from the following description of the invention, a description given by way of example only, with reference to the appended drawings in which:

    In a configuration visible in Figure 1 for example, the channel 12 comprises a horizontal bottom 14 and two side walls 16, 16 'substantially vertical, the bottom and the two side walls 14, 16, 16' being parallel to the longitudinal direction. According to the variants, the junction zone between the bottom and each side wall may form a right angle or be rounded. According to another variant, the channel comprises only a bottom 14 with a curved profile, for example in an arc.
    The scraper device comprises a frame 18 configured to move in the channel 12 in the longitudinal direction, at least one scraper 20 supported by the frame 18 and a cable 22 connected to the frame 18 configured to move the frame in the longitudinal direction in a first direction, called scraping direction and visible in Figure 2, and in a second direction opposite to the first direction, called return direction and visible in Figure 3. For the remainder of the description, the front and rear reference in the sense of scraping.
    The cable 22 is associated with a mechanism for moving the cable along the channel 12 in the first direction or in the second direction. The cable 22 and the movement mechanism are not further described because they may be identical to those of the prior art.
    According to a characteristic of the invention, the chassis 18 comprises at least three wheels 24 configured to roll on the bottom 14 of the channel 12. Thus, the chassis rolls on the bottom of the channel and no longer slips as in the prior art which limits the risk of premature wear of the channel 12. Preferably, the frame 18 comprises four wheels 24, two arranged in a front transverse plane and two others in a rear transverse plane. According to one configuration, the chassis comprises two longitudinal members 26, 26 'oriented in the longitudinal direction, each supporting at each of its ends a wheel 24.
    According to one embodiment, each spar 26, 26 'is in the form of a plate disposed in a vertical plane and which comprises a substantially horizontal central portion 28, and at each end of the central portion, an arm 30, 30 inclined towards the bottom 14 of the channel 12. The free end of each arm 30, 30 'supports an axis of rotation A24 of one of the wheels 24, said axis of rotation A24 being substantially horizontal and oriented perpendicularly to the longitudinal direction .
    According to another characteristic of the invention, the chassis 18 comprises a self-centering system in the channel 12. This self-centering system comprises at least three guide wheels 32 configured to bear against the two side walls 16 and 16 'of the channel. Preferably, the self-centering system comprises four guide wheels 32, two for each side wall 16, 16 'of the channel 12.
    According to one embodiment, the frame 18 comprises two crosspieces 34, 34 ', a first crosspiece 34 disposed in a first transverse plane, a second crossbar 34' disposed in a second transverse plane remote from the first plane. Preferably, the cross members 34, 34 'are connected to the two longitudinal members 26, 26' and positioned at each end of the central portion 28 of the two longitudinal members.
    Advantageously, the self-centering system is adjustable in width in order to adapt it to different widths of channel 12.
    According to one embodiment, each crossbar 34, 34 'comprises a hollow tube 36 connected to the longitudinal members 26, 26' and two extensible arms 38 which slide at each end of the hollow tube 36, the free end of each extensible arm 38 supporting a vertical axis of rotation A32 of one of the guide wheels 32. A locking element 40 such as a screw, for example, is used to immobilize in translation each extensible arm 38 with respect to the hollow tube 36.
    Preferably, the frame 18 comprises reinforcements 41, each connecting a cross member to a spar. According to one embodiment, the frame 18 comprises two reinforcements 41, a first which connects the cross member 34 to the spar 26 and a second which connects the cross member 34 to the spar 26 '. The invention is not limited to this embodiment to stiffen the frame 18.
    The scraper 20 can pivot relative to the frame 18 between an active position visible in Figure 2 in which the scraper 20 is disposed in a substantially transverse plane and a raised position visible in Figure 3 in which the scraper 20 is inclined and separated from the bottom 14 of the trough 12 in operation. For this purpose, the scraper 20 is connected to the frame 18 by at least one pivoting connection which comprises a pivot axis A20 substantially horizontal and disposed in a transverse plane in operation.
    Preferably, the scraper device comprises two coaxial pivoting links, one for each spar 26, 26 '. Advantageously, each pivoting connection is removable so that the scraper 20 can be separated from the frame 18 in order to facilitate maintenance.
    According to one embodiment, for each pivoting connection, the scraper 20 comprises a tab 42 which extends in a plane parallel to the longitudinal members 26, 26 ', disposed near one of the longitudinal members 26, 26'. In addition, each pivoting connection comprises an axis of rotation 44 which passes through a tab 42 and the adjacent spar 26 or 26 ', the axis of rotation comprising at a first end a head and at a second end a through hole in which It accommodates a pin 46. Thus, in order to disassemble the scraper 20, it suffices to remove the pins 46 and then the axes of rotation 44.
    Advantageously, the scraper 20 comprises a rectangular or square rigid plate 48 which comprises a lower edge 50, two lateral edges 52, 52 'and an upper edge 54, in operation the lower edge 50 and the two lateral edges 52, 52' being oriented respectively towards the bottom 14 and the side walls 16,16 'of the channel 12.
    Preferably, the rigid plate 48 is dimensioned so that at least the lower edge 50 is spaced from the bottom 14 of the channel 12, when the wiper 20 is in the active position. In addition, the scraper 20 comprises at least one flexible band 56 fixed at least at the level of the lower edge 50, which protrudes with respect to the rigid plate 48 and which is dimensioned so as to come into contact with the bottom 14 of the channel 12 when the scraper 20 is in the active position. By way of example, the flexible band 56 is made of rubber or a similar material.
    This flexible band 56 makes it possible to limit the wear of the channel 12.
    Advantageously, this flexible strip 56 is a wear part and is connected to the rigid plate 48 by a removable connection. For example, the flexible strip 56 is clamped between the rigid plate 48 and a plywood 58 connected by bolts.
    Advantageously, the lower edge 50 and the lateral edges 52, 52 'of the rigid plate are spaced from the bottom 14 and the side walls 26, 26' of the channel when the scraper is in the active position. In addition, the scraper 20 comprises three flexible bands 56 positioned at the lower edge 50 and the two lateral edges 52, 52 '.
    According to a characteristic of the invention, the pivot axis A20 of the pivoting connection connecting the scraper 20 to the frame 18 is positioned so that the mass of the scraper 20 is distributed in a balanced manner on either side of the axis. pivoting A20. According to one embodiment, the pivot axis A20 is positioned approximately equidistant from the lower edges 50 and upper 54. This configuration reduces the forces required to cause the transition from the active position to the raised position or vice versa.
    The upper edge 54 of the scraper comprises notches 59 to allow the passage of the longitudinal members 26, 26 ', especially when the scraper is active position.
    The scraper device comprises a control 60 for causing the passage of the wiper from the active position to the raised position or vice versa.
    This control 60 comprises a rod 62 connected to the cable 22 and movable relative to the frame in the longitudinal direction between a first position corresponding to the active position of the scraper 20 and a second position corresponding to the raised position of the scraper 20. The rod 62 is connected to the frame 18 by a slide connection.
    According to one embodiment, the bead wire 62 has a length greater than the distance separating the two cross-members 34, 34 '. This rod 62 can slide in the longitudinal direction relative to the cross members 34, 34 '. For this purpose, each crossbar 34, 34 'comprises a guide 64, 64' in the form of an Omega shaped rider whose two ends are connected to the cross member and whose central portion is spaced from the cross member so to form with the crossbar 34, 34 'a passage in which the rod 62 can slide.
    Preferably, the bead wire 62 is positioned parallel and equidistant from the longitudinal members 26, 26 'to improve the guiding of the frame 18 in the channel 12.
    Advantageously, the rod 62 is connected to the cable 22 by two cable clamps 66, 66 '. These two cable clamps 66, 66 'are positioned on the rod 62 so that a first cable clamp 66 is in contact with the guide 64 located at the front, which corresponds to the first position, when the chassis 18 moves in the scraping direction, as shown in FIG. 2 and that a second clamp 66 'is in contact with the guide 64' located at the rear, which corresponds to the second position, when the frame 18 moves in the return direction as shown in Figure 3.
    The connection between the bead wire 62 and the frame 18 comprises a first abutment, for example the first guide 64 against which abuts the cable clamp 66, which is configured to immobilize the bead wire 62 relative to the frame 18 in the first position ( active position of the scraper) and a second stop, for example the second guide 64 'against which abuts the cable clamp 66', which is configured to immobilize the bead wire 62 relative to the frame 18 in the second position (raised position of the scraper).
    According to a characteristic of the invention, the control 60 comprises a rod 68 which connects the rod 62 and the scraper 20. This design makes it possible to obtain a positioning of the scraper 20 substantially horizontally in the raised position. According to another point, the link 68 makes it possible to convert a very short translation movement of the rod 62 into a consequent pivotal movement of the scraper 20 which passes from a vertical position to a horizontal position.
    Advantageously, the rod 68 is parallel to the longitudinal direction and positioned at the front of the scraper 20, between the guide 64 located at the front and the scraper 20. According to one configuration, the rod 68 is connected to the rod 62 and to the rod. scraper 20 so that the link 68 is approximately horizontal in the active position and inclined in the raised position.
    According to another feature, with the exception of the flexible strips 56 and wheels 24 and 32, the other elements of the frame 18 and the scraper 20 are made of a material resistant to animal waste, such as stainless steel.
    According to another characteristic of the invention, the scraping device comprises at least one cable holding system 70 making it possible to keep the cable 22 away from the bottom 14 of the trough 12. Generally, the scraper device comprises several holding systems of the trolley 12. cable 70 which are distributed along the length of the channel 12.
    Each cable holding system 70 comprises a support 72 positioned above the cable 22 and a hook 74 connected to the support 72 by a pivoting connection 76 allowing the hook 74 to pivot about an axis of rotation A76 oriented in the longitudinal direction. between a holding position visible in Figures 4 and 6A and an avoidance position visible in Figures 5 and 6B.
    According to one embodiment, the support 72 is a cross-member 78, positioned in a transverse plane, the ends of which rest on the ground 10 on either side of the channel 12 and a vertical upright 80 whose upper end is connected at the cross member 78 and whose lower end supports the pivotal connection 76.
    The hook 74 comprises an L-shaped plate 82, a first leg 84 of the L being connected to the vertical upright 80 by the pivoting connection 76 and the other leg 86 supporting a finger 88 parallel to the first leg 84. The plate 82 and the finger 88 are arranged in a transverse plane. Preferably, the finger 88 comprises a coating promoting the sliding of the cable 22 and limiting its wear.
    According to one embodiment, the pivoting connection 76 comprises an axis of rotation 90 which passes through the vertical upright 80 and / or the plate 82. This axis of rotation 90 is parallel to the cable 22 and disposed in line with the latter.
    The hook 74 and the pivoting connection 76 are configured so that the free end 92 of the finger 88 is higher than the remainder of the finger 88. Thus, in the holding position, the finger 88 is inclined so that the cable tends to slide towards the plate 82 and not toward the free end of the finger 88.
    In addition to the pivoting hook 74, the chassis 18 includes an avoidance system 94 capable of pivoting the hook 74 in the avoidance position when the chassis 18 passes. This avoidance system 94 comprises a slideway 96 connected to the frame 18 This slideway 96 comprises a strip positioned in a vertical plane which comprises a central portion 98 oriented in the longitudinal direction and two sides 100, 100 'inclined at each end of the central portion 98.
    According to one embodiment, the slideway 96 is connected by two tabs to the cross members 34, 34 '.
    The central portion 98 of the slide 96 is offset relative to the rod 92 in the transverse direction. More particularly, the central portion 98 of the slideway 96 is positioned between the axis of rotation 90 and the second branch 86 of the hook 74 so as to cause the hook 74 to pivot in the avoidance position when the chassis 18 passes.
    The panels 100, 100 'are inclined in the direction of the bead wire 62. They are sufficiently long to bear against the first branch 84 under the axis of rotation 90 and cause the hook 74 to pivot.
    Advantageously, as illustrated in Figures 7, 8A to 8E, the scraper device comprises at least one shim 102 which is fixed on the bottom 14 of the channel 12, which is positioned on a path of at least one wheel 24 of the frame 18 and which is configured to retain said wheel 24 during the translation of the rod 62 relative to the frame 18 to force the change of position of the scraper.
    The doctoring device comprises a first wedge 102 (visible in FIGS. 8A to 8E) which is configured to retain at least one of the wheels 24 during the translation of the rod 62 relative to the chassis 18 of the second position which corresponds to the position raised from the scraper 20 to the first position which corresponds to the active position of the wiper 20. This first shim 102 makes it possible to force the wiper 20 to move from the raised position to the active position.
    This first wedge 102 is positioned near one end of the trough 12 at which the scraper device changes direction of travel and goes back to the scraping direction, at least one of the wheels 24 of the frame 18 being positioned between the first wedge 102 and the end of the channel 12 corresponding to the change of direction of movement from the return direction to the scraping direction.
    The first shim 102 comprises in the scraping direction 104 (visible in FIG. 8A), a first, strongly inclined pan 106 configured to retain the wheel 24 as long as the rod 62 is not in contact with the first stop 64, and a second pan 108 slightly inclined configured to let the wheel 24 effortlessly.
    If necessary, the scraper device may comprise a second shim which is configured to retain at least one of the wheels 24 during the translation of the rod 62 relative to the chassis 18 from the first position to the second position. This second wedge makes it possible to force the passage of the wiper from the active position to the raised position. However, in the active position, the friction between the scraper 20 and the walls of the channel 12 are greater than the friction between the rod 62 and the frame 18 so that this second wedge is not generally useful.
    This second shim is positioned near one of the ends of the trough 12 at which the scraper device changes direction of travel and goes from the scraping direction to the return direction, at least one of the wheels 24 of the chassis 18 being positioned between the shim and the end of the channel 12 corresponding to the change of direction of movement of the scraping direction in the return direction.
    The second spacer comprises in the return direction 110, a first pan 106 strongly inclined configured to retain the wheel 24 as the rod 62 is not in contact with the second stop 64 ', and a second pan 108 slightly inclined configured to leave pass the wheel 24 without effort.
    The operation of the scraping device is now described.
    When the cable 22 is pulled in the direction of traction as illustrated in Figure 2, the cable clamp 66 is in contact with the guide 64 located at the front. The rod 62 is in the first position and the scraper 20 is in the active position. The frame 18 and the scraper 20 are translated into the channel 12 by driving the droppings and other waste.
    The cable 22 is held by a hook 74 as illustrated in FIG. 4. When the chassis 18 arrives at the approach of a hook 74, the panel 100 of the slideway 96 situated at the front bears against the hook 74. The combination of the inclination of the pan 100 and the advance of the chassis 18 causes the hook 74 to pivot in the avoidance position as shown in FIG. 6B. After the passage of the central portion 98 of the slide 96, the hook 74 is in abutment against the pan 100 'located at the rear. The combination of the inclination of the pan 100 'and the advance of the chassis 18 causes the pivoting of the hook 74 which passes from the avoidance position to the holding position. During this pivoting movement, the hook 74 re-grips the cable 22 and holds it again.
    When the cable 22 is pulled in the return direction as shown in Figure 3, the rod 62 is translated to the second position until the cable tie 66 'bears against the guide 64' at the rear . This movement of the rod 92 causes the pivoting of the wiper which passes from the active position to the raised position. If necessary, the second shim 102 'makes it possible to force this movement of translation of the rod 92 from the first position which corresponds to the active position of the scraper 20 to the second position which corresponds to the raised position of the scraper 20. The frame 18 and the scraper 20 are translated into the channel 12, the scraper 20 being in the raised position.
    When the frame 18 arrives at the approach of a hook 74, the pan 100 'of the slide 96 located at the back bears against the hook 74. The combination of the inclination of the pan 100' and the advance of the frame 18 causes the hook 74 to pivot in the avoidance position as illustrated in FIG. 6B. After the passage of the central portion 98 of the slideway 96, the hook 74 is supported against the pan 100 located at the front. The combination of the inclination of the pan 100 and the advance of the frame 18 causes the pivoting of the hook 74 which passes from the avoidance position to the holding position. During this pivoting movement, the hook 74 re-grips the cable 22 and holds it again.
    When the scraping device arrives close to the end of the channel 12 corresponding to the passage from the raised position to the active position as illustrated in FIG. 8A, the wheel 24 rolls on the second, slightly inclined pan 108 of the first block 102 as shown in FIG. 8B. Following, the wheel 24 is positioned between the first wedge 102 and the end of the channel 12. To cause the displacement of the scraper device, the direction of traction of the cable 22 is reversed. It is then pulled in the scraper direction 104. Because of the friction between the bead wire 62 and the frame 18, the bead wire 62 can remain in the second position, in contact with the second stop 64 'which corresponds to the raised position of the 20. When the wheel 24 comes into contact with the first panel 106, as illustrated in FIG. 8C, the first spacer 102 holds the chassis 18 so that traction on the cable 22 in the scraping direction 104 causes the translation the rod 62 to the first position until it comes into contact with the first stop 64 as shown in Figure 8D. After the passage of the first shim 102, the scraper 20 is in the active position as illustrated in FIG. 8E.
